RT Journal Article ID 549cb3b43744d851 A1 Tkachenko, Alexander I. T1 On the Problem of In-Flight Geometric Calibration Using Unknown Landmarks JF Journal of Automation and Information Sciences JO JAI(S) YR 2014 FD 2014-03-14 VO 46 IS 1 SP 42 OP 52 K1 on-board opto-electronic complex K1 in-flight geometric calibration by unknown landmarks K1 in-flight alignment of the camera and star sensor K1 accuracy and disturbing factors. AB This article is initiated by the publication of the proposed by D.V. Lebedev method of in-flight geometric calibration of the on-board opto-electronic complex of a spacecraft by observations of unknown landmarks. Adverse effect of disturbing factors on the accuracy of determining the mutual attitude of the imaging camera and star sensor in the case of the spacecraft by images of the mentioned landmarks are studied. The means to weaken this effect are proposed. PB Begell House LK https://www.dl.begellhouse.com/journals/2b6239406278e43e,4bfafed4554514ac,549cb3b43744d851.html
